Cannot output to bluetooth speaker

[platten]

Hello,

I would like to output airplay (and the web radios) to an attached bluetooth speaker. Airplay connects but no audio is playing. When trying to play webradios I get the following error message: Failed to open "ALSA Bluetooth" (alsa); Failed to open ALSA device "_audioout": Invalid argument

My moodeutl -l output is the following:

Moode can only receive an AirPlay stream and output to a local audio device, it cannot send an AirPlay stream to a remote host.

I thought output could go to a Bluetooth speaker....

   

[Tim Curtis]

It can but only from MPD.

ETA: Renderers for example AirPlay can also play to moode and be routed via the Bluetooth connection to a remote Speaker.

I just ran a quick test and it seems to work ok

I see that it works for you, but unfortunately it does not for me. Any ideas on how I can diagnose and resolve this?

I was able to play a wav file using this:  aplay -D bluealsa /usr/share/sounds/alsa/Front_Center.wav but unfortunately it does not work for airplay or when trying to stream webradio.

There is no manual configuration involved. When the output option in Bluetooth Control is set to "Bluetooth speaker" it configures the _audioout.conf ALSA device which is used by MPD and the renderers to route PCM data to the ALSA device named "bitstream" which is the Bluetooth connection.

Code:

pi@moode9:~ $ cat /etc/alsa/conf.d/_audioout.conf

pcm._audioout {

slave.pcm "btstream"
